Answers

Answer 1

Answer:

x = 118 degrees approximately

Step-by-step explanation:

Here, we want to get the measure of the angle marked x

We shall use the side facing it and apply the cosine rule

The side facing the angle measures 90

Thus, we have it that;

90^2 = 55^2 + 50^2 - 2(50)(55) cos X

2575 = - -5,500 cos X

X = cos^-1(-2575/5,500)

X = 118 degrees approximately

Can anyone help me and put the explanation please and thank you

Answers

Ok
So to solve number 1 spur x as the subject.

1) x + 9 = - 15
x = - 15 — 9
x = - 24

To know if it is correct you can say;

- 24 + 9 = - 15

Because you got back - 15 then it is correct.

2) 11x = 121

Again we are gonna make x the subject.

11x = 121
x = 121/11
x = 11

If you should do the opposite of division and multiply 11 by 11 you should get 121.

3) 30 = 8n — 2

Make n the subject

30 = 8n — 2
30 + 2 / 8 = n
4 = n

I’ll add the rest of the solutions in the comments. :) Hope this helps

Step-by-step explanation:

the equation on finding slope is y2 - y1/x2 - x1

so it is...

6 - 6 = 0

6 - -5 = 11

0/11 but that doesnt work so I believe the slope is zero because the denominator is not the one being a 0

The width of a rectangle is 5n−2.5 feet and the length is 2.5n+6 feet. Find the perimeter of the rectangle.

Answers

Answer:

5.0n+7.0

Step-by-step explanation:

Perimeter of a rectangle = 2(L+W)

L is the length = 5n-2.5

W is the width = 2.5n+6

Perimeter of the rectangle = 2(5n-2.5+2.5n+6)

Perimeter of the rectangle = 2(2.5n+3.5)

Perimeter of the rectangle = 5.0n+7.0

Hence the perimeter of the rectangle is 5.0n+7.0
